I work next to the Orbitec office. The weird grow lights are visible from the parking lot. Owner drives some crazy kind of electric sports car that he charges with a long-ass extension cord. Interesting equipment out back for venting gases...every so often...PHOOOOOSH PHOOOOOSH PHOOOOSH!!!!

Pinkhouses are replacing greenhouses. More correctly, Magenta light, not pink. Plants, it turns out, do the majority of their photosynthesis using red and infrared light, plus *some* blue, those "full spectrum" bulbs are wasted on plants but good for people.

Meanwhile, you can make low-heat, power-efficient LED lights in magenta, and put the lights almost right up against the leaves, no wasted space lighting the room, just the plant. There's an operation like this somewhere in/near Ontario, a warehouse with racks and racks of hydroponic lettuce grown under magenta or "pink" light, and it can crank out the equivalent on ten acres in the footprint of just one. Imagine indoor farms like this for other crops, located inside cities, thus eliminating most of the costs for transporting the food to the people eating it. Growing indoors also means a controlled environment that means no bugs, so no pesticides needed, and no weather damage from storm or drought.

Interesting. I though they used mostly red spectrum for plant growth, but then during fruiting season used mostly blue spectrum. This would be great for lettuce, but I wonder how tomatoes would do.
